Let's divide 81817255 by 220
Our goal is to divide 81817255 by 220.

Let's proceed to step 1:
The number 220 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 220

On to step 2:
If we divide 81 by 220, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 220

Advancing to step 3:
When dividing 818 by 220, we get 3 with a remainder of 158.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 660 from 818 to get 158.
Fetch the next digit (1) from the dividend, attach it to 158 and continue: 1581 / 220

Let's proceed to step 4:
220 goes into 1581 7 times with a remainder of 41.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 41 after subtracting 1540 from 1581.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 220

Going ahead to step 5:
If we divide 417 by 220, we get 1 and a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 371.0
Subtracting 220 from 417 leaves us with 197.
Fetch the next digit (2) from the dividend, attach it to 197 and continue: 1972 / 220

Going ahead to step 6:
The number 220 fits into 1972 8 times, leaving a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 3718.0
Deduct 1760 from 1972 and we're left with 212.
Bring next digit (5) of the dividend behind the 212 and repeat the process: 2125 / 220

Moving on to step 7:
220 goes into 2125 9 times with a remainder of 145.
The number 9 becomes the next digit in our result. 
Result so far: 37189.0
The remainder is 145 after subtracting 1980 from 2125.
Bring next digit (5) of the dividend behind the 145 and repeat the process: 1455 / 220

Let's proceed to step 8:
220 can be fit into 1455 6 times, resulting in a remainder of 135.
Put 6 as the next digit of the answer. 
Result so far: 371896.0
If we take 1320 away from 1455, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Going ahead to step 9:
When dividing 1350 by 220, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 371896.6
Subtracting 1320 from 1350 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
220 goes into 300 1 times with a remainder of 80.
Put 1 as the next digit of the answer. 
Result so far: 371896.61
The remainder is 80 after subtracting 220 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
If we divide 800 by 220, we get 3 and a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 371896.613
Deduct 660 from 800 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
1400 divided by 220 is 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 371896.6136
Subtracting 1320 from 1400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
If we divide 800 by 220, we get 3 and a remainder of 140.
Put 3 as the next digit of the answer. 
Result so far: 371896.61363
Deduct 660 from 800 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 14:
1400 divided by 220 is 6 with a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 371896.613636
Subtracting 1320 from 1400 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 15:
800 divided by 220 is 3 with a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 371896.6136363
If we take 660 away from 800, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 16:
If we divide 1400 by 220, we get 6 and a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 371896.61363636
If we subtract 1320 from 1400, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 371896.61363636, and the remainder is 8e-08.
